The natural history of plants, their forms, growth, reproduction, and distribution; . \i- ¥1 XM^l^^. ^H. Fig. 47.—Bushes of Mistletoe upon tlie Black Poplar iu winter. The development of the first year ends with the formation of this the winter is over, the branch, into which the sinker is inserted so as justto reach the wood with its point, grows in thickness, a new layer of wood-cells—aso-called annual ring—being superimposed upon the wood of the previous increasing mass of wood first surrounds the tip of the sinker with wood-cells,then forms a rampart all round it, pushing the cortical tissue, wherein that organhas hitherto been wedged, in front of it in an outward direction, and in this waythe sinker is at length fixed deep within the woody cylinder. The process ofinclosure by the wood-layers, as they are built up, may be compared to the gradualsurrounding of a stake on the sea-shore by the rising tide; the lowermost extremityis first immersed and then higher and higher parts until the whole is enveloped.
